ANALYSIS OF MOUTHWASH Background Information: Commercial mouthwashes are mixtures of water‚ alcohol‚ dyes‚ flavorings‚ and other compounds. In this experiment‚ you will use gas chromatography to determine the alcohol content of the mouthwash. Since the volumes of alcohol and water are not additive when mixed‚ a calibration curve must be used. It will provide the correction factor needed for alcohol-water mixtures. The calibration curve will be prepared by placing a known amount of alcohol

EXPERIMENT 3: ISENTROPIC EXPANSION PROCESS Objective In order to demonstrate the isentropic expansion process. Introduction Isentropic means no change in entropy. Entropy is a thermodynamic property that is the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work. In simple terms‚ the measure of the level of disorder in a closed but changing system‚ a system in which energy can only be transferred in one direction from an ordered state to a disordered

Exhaust Gas Recirculation 1. INTRODUCTION All internal combustion engines generate power by creating explosions using fuel and air. These explosions occur inside the engine’s cylinders and push the pistons down‚ which turns the crankshaft. Some of the power thus produced is used to prepare the cylinders for the next explosion by forcing the exhaust gases out of the cylinder‚ drawing in air (or fuel-air mixture in non-diesel engines)‚ and compressing the air or fuel-air mixture before the fuel is

Experiments: Doctors‚ Experiments‚ and Results Melissa Anjeanette Edwards POLYTECH High School of Kent County‚ Woodside‚ Delaware Abstract During World War II experiments were done on the prisoners of war in Nazi Germany. Doctors for these camps came in all shapes and sizes including former S.S. Troops‚ Women‚ and a variety of prisoner doctors. The experiments differed as much as the doctors themselves; however they stayed the same in one factor‚ medical curiosity become killing in atrocious

Data and Conclusions: The purpose of this experiment was to learn how to use distillation and gas chromatography to separate and identify different compounds from a given mixture. There are several kinds of distillation methods. However‚ the method that we used in this experiment was fractional distillation. This method is used when trying to separate two different volatile compounds whose boiling points differ by 40-50°C or more. If the boiling points are too close‚ this method

Orsat Gas Analysis Experiment I. Objectives To analyze the dry exhaust gas (DEG) from a combustion system using the Orsat apparatus. II. Apparatus As shown in figure‚ the Orsat apparatus consists of a water-jacketed 100-m1 burette B connected at its top to a glass manifold M and at its bottom to a leveling bottle L. The glass manifold M is connected to three reagent bulbs called pipettes P1‚ P2 and P3 via three cocks C1‚ C2 and C3. Each tube is filed with its own absorbing chemical solution:
